Compressor & Blower
Compressor & Blower
We design whole compressed air systems consisting of compressor, blower as well as ancillary equipment such as pre coolers, dryers, filters, receiver tanks, closed cooling systems, chilled water systems as per the client's requirements. For the optimum performance of the compressed air system, the package integration is important. Our major experiences are focused on integrating compressors with a structural common skid, dryer & filters, receiver tank, interconnecting piping & valves, tubing, instruments, electric and control system (PLC). All systems complete assembled, integrated and tested in our shop. Specific performance, size and requirements of products are available upon request.
